WEATHER-STRIP AND DOOR-STOP.

SPECIFICATION forming art of Letters Patent No. 558,786, dated April 21,1896. Application filed November 26, 1895. Serial No. 570,241- (Nomodel.)

To aZZ whom it may concern.-

Be it known that I, ADOLPHUS M. DOYLE, of Leoti, in the county of\Vichita and State of Kansas, have invented a new and Improved"Weather-Strip and Door-Stop, of which the following is a full, clear,and exact description.

My invention relates to a combined weatherstrip and stop adapted for usein connection with doors and to be operated through the medium of aknob-spindle, and the object of the invention is to so combine the stopand weather-strip that they will operate together, and wherebythey maybe readily and conveniently applied to a door and constructed in anexceedingly economic and simple manner.

A further object of this invention is to provide a connection betweenthe door-stop and the knob-spindle of such character that the connectionwill not interfere with turning the spindle in either direction, andwhereby the door-stop may be raised from engagement with the floor nomatter whether the knob be turned to the right or to the left.

struction and combination of the several parts, as will be hereinafterfully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a perspective view of the lower portion of a door,illustrating the door open and held open by the stop. Fig. 2 is alongitudinal section through a portion of the door, the said sectionbeing taken practically on the line 2 2 of Fig. 8, illustrating theweatherstrip in engagement with the threshold-strip. Fig. 3 is a partialside view of the door, the stop and weather-strip being in the positionshown in Fig. 2, and in this view a portion of the casing of the stop isbroken away. Fig. 4c is a vertical section through a portion of the doorand likewise a vertical section through the attachment, the stop beingshown in the position to hold the door open, or partially open, and thesection being taken substantially on the line 4: l of Fig. 5. Fig. 5 isa perspective view of a portion of the door and of the attachment, theparts being in the position shown in Fig. 4 and the knob-spindle beingin section; and Fig. 6 is an outer face view of a portion of the door,the said door being closed and a portion of the improvement shown inposition thereon.

In carrying out the invention a horizontal pocket 10 is produced in thebottom edge of the door A, to which the attachment is to be made, and aweather-strip B islocated within said pocket, being pivoted near theupper edge of its inner or rear end, as shown at 11 in Fig. 1. Thepocketis of such size that the weatherstrip may have vertical movementtherein to a limited extent, and that portion of the pocket between theupper edge of the weatherstrip and the upper wall of the pocket isclosed at the outer end of the pocket by a dustguard 12, whichpreferably consists of a metal plate properly countersunk in the frontV61" tical edge of the door.

Adjacent to the front vertical edge of the door, at the bottom thereof,the stop C is located. The stop consists of a casing let, preferably ofsubstantially cylindrical form, being provided with side flanges wherebythe casing is screwed or otherwise secured on the door. In the bottomportion of the rear face of the casing 14 a longitudinal slot 15 ismade, and this slot is in communication with a transverse slot 16 madein the door, and the said transverse slot 16 is preferably widest atthat end which is in communication with the caslug-slot.

A pin 17 is pivoted in the transverse slot of the door, and the said pinis of sufficient length to extend from one end of the slot to the other,and through the slot 15 in the casing and a predetermined distancewithin the latter. This pin likewise passes through an opening oraperture 18 made in the Weatherstrip, the opening being larger than thediameter of the pin. The pin 17 may be pivoted upon the door in anysuitable or approved manner. One means of accomplishing this result isshown in Figs. 2 and 6, in which it will be observed that a staple 19 issecured upon the outer face of the door by bending its legs to formspurs, the said spurs being driven into the door, and the bow-section ofthe staple is made to pass through an opening in the pin. A second andsmaller staple 20 is then driven in the door and made to cross the mainstaple 19, holding the latter firmly in place.

The stop 0 consists of a body portion 21 and The bodypor a reduced orshank section 22.

tion 21 is made to conform in cross-section to the cross-section of thecasing and has verti cal movement therein, and in the lower portion ofthe said body an opening 23 is made, which receives the free end of thepin 17, as shown in Figs. 2 and 4, while upon the bottom portion of thebody of the stop an elastic facing 24: is securely fastened, and thisfacing is in the nature of a block, extending even when the stop is inits extreme upper position below the lower end of the casing 14, whichis open, and the facing 24, which is preferably made of rubber orleather, has that face inclined which is presented to the door, theinclination corresponding substantially to the angle of thethreshold-strip over which the stop must pass. The spindle-section ofthe stop passes through a suitable opening in the top of the casing, andwithin the casing the said spindle-section is surrounded by a spring 25,the said spring having bearing against the upper end of the casing andlikewise against the shoulder formed at the junction of the body and thespindle of the stop.

An elongated slot 26 is produced longitudinally in the outer end of thespindle of the stop, and a crank-arm or crank-plate 27 is secured uponthe knob-spindle 28 of the door, the lower end of which crank-arm isadjustably connected to the upper end of the stop by means of a link 28,the said link being passed through the slot 26 in the upper end of thestop and is capable of free movement therein.

In the operation of the stop and weatherstrip, no matter whether theknob-spindle is turned to the right or to the left, the stop will bedrawn upward, compressing the spring 25. Therefore, supposing the stopto be in engagement with the floor to hold the door in open position, asshown in Figs. 4: and 5, by turning the knob-spindle to the right or tothe left the stop will be drawn upward, and the pin 17, connected withthe stop, which had been in a downwardly-inclined position, will beraised to a substantially horizontal position, carrying theweather-strip upward with it. The door may now be closed, and the stopwill have been carried a suificient distance above the floor to clearthe threshold-strip, thereby not chafing any carpet that may be laidupon it, and when the door is fully closed and the spindle released thespring will force the stop down firmly upon that portion of the pin 17which enters the stop, carrying the pin to a firm bearing on the bottomwall of the slot 18 in the weather-stri p through which the said pin ispassed, and forcing the said strip downward to a firm contact with thethresholdstrip, as shown in Fig. 2.

In order to open the door, the spindle may be turned either to the rightor to the left, since the connecting-rod 28 will simply play loosely inthe slot 26, which is of sufficient length to permit of the proper throwof the crank-arm or crank-plate 27.

In manipulating the spindle when the door is closed, at the end of thestroke of the said crank plate or arm 27, the stop will be carriedupward a sufficient distance to draw the pin 17 also upward, and therebyslightly raise the weather-strip, so that it will not scrape along thethreshold-strip or its covering as the door is opened. When the door hasbeen opened as wide as desired and the knob-spindle is released, thespring 25 in the casing will force the stop downward to an engagementwith the floor, and the weather-strip will be permitted to drop likewisea predetermined distance, as shown in Figs. 1 and 5.

The weather-strip is preferably provided at its bottom with a facing ofa yielding material, such as leather or rubber. It is evident that theknob-spindle will turn sufficiently to permit of the connecting-rod 28to straighten itself as the spring forces the stop downward to anengagement with the floor, as shown in Figs. 1, 4, and 5. If in practiceit is found desirable, the crank arm or plate may be omitted and thewire of the connecting-rod 28 may be attached directly to theknob-spindle.

Ilavin g thus described my invention, I claim as new and desire tosecure by Letters Patent 1. The combination of a stop adapted forattachment to a door, a spring normally exerting pressure downward onthe said stop, a weather-strip adapted for pivotal connection with thedoor, and a pin likewise adapted for pivotal connection with the door,the said pin being passed through the weather-strip to an engagementwith the said stop, the engagement being so made that the said pin willcommunicate the pressure from the spring controlling the stop to theweather-strip, as and for the purpose specified.

2. The combination of -a vertically-movable stop, a pivotally-mountedweather-strip having an opening therein, and a pin pivotally mounted offthe stop and weather-strip, the pin being passed through the opening inthe weather-strip and having loose connection with the stop,substantially as described.

3. The combination with a door having a slot extending through a portionof the door and communicating with the lower edge there of, the dooralso having a triangular passage intercepting the slot, a pin having oneend pivotally mounted in the small end of the triangular passage andpassed through the same and projecting beyond the door, a weatherstrippivotally mounted within the slot and having an opening through whichthe pin is passed, a casing extending vertically with the door andsecured to the side opposite the side to which the pin is pivoted, and astop vertically movable in the casing and having loose connection withthe pin, substantially as described.
